I have a LGD. Her name is Ava (Avalanche), a Maremma/Pyrenees mix. She lives full time with a small herd of nigerian does. She still a pup really. Anyway one day I was moving fencing around and had the gate to the pen temperarly tied with 2 pieces if twine. I noticed one was missing, so I tied another on. Ava promptly untied it and walked away! So I thought, "Well this is a fluke". I got my phone ready to take a video (in case she just happened to repeat it). I tied the twine. And she did it again! I got it on video.
